CAUTION: The format of the publication (COTW) allows only limited loading data to be given. Missing is information very important to the person handloading the cartridge, such as cartridge overall length (COL), cases used, primers, and barrel length. (The above loads were developed using Winchester standard large rifle primers and fired in a Marlin XS7 rifle sporting a 22-inch Shilen barrel with a 1 in 14 twist.) Also, when loading cartridges with heavy powder charges the author normally taps the case gently on the loading bench as the weighed powder charge is poured into the case mouth through a small funnel. This is done to settle the heavier powder charges and AVOID compressed loads. It is again emphasized that the loads given above are considered MAXIMUM loads, even though COTW does not specifically state that. (Read the COTW Disclaimer and Warning on page 6.) Handloaders should NOT start out using MAXIMUM loads. It is often recommended that they start at a listed Starting Load, or about 5 PERCENT BELOW maximum loads, and carefully work up in small increments ONLY if pressure signs indicate it is OK.

Please note that the author is not specifically recommending any particular load. But, he is giving some of his observations and thinking. The individual handloader and shooter must realize that there are inherent risks in those activities that are beyond the control of the author and that the author assumes no liability whatsoever for use of the information posted.
